Compact MEMS vibration analyzer simplifies equipment monitoring

The MEMS-based ADIS16227 iSensor vibration monitor is a fully integrated three-axis vibration analyzer with programmable embedded processing that is capable of autonomous operation. The component lets engineers easily design monitoring capability into systems ranging from wind turbines to precision factory automation and assembly equipment, thereby permitting early detection, identification, and isolation of vibrations that lead to poor operation or equipment downtime.

Combining triaxial sensor, data conversion, and processing technologies with data capture and a serial peripheral interface (SPI), the compact, 15-mm cube can sample, process, and store time-stamp x, y, and z acceleration data into the FFT buffer and record. The programmable digital filter offers low-pass configuration options, and an internal clock drives the data-sampling system during data capture, eliminating the need for an external clock.The compact device can be placed close to a vibration source for early detection of small signals in a repeatable way, avoiding data discrepancies due to differences in location or mechanical coupling.

Six configurable spectral alarm bands and windowing options allow analysis of the full frequency spectrum with two types of alarms (warning threshold and fault threshold) for earlier and more accurate detection of problems. The device’s four programmable input ranges (0 to 1g, 5g, 20g, and 70g) allow support of multiple operational scenarios, improve the precision of FFT, and aid in observing lower-level signals. The unit’s triaxis wide-band (22-kHz resonance) acceleration sensing is configurable for rates to 100 ksamples/s, and averaging/decimation options allows more accurate assessment of subtle vibration profile changes.
